Loading nested resource encrypted fields crashes ash_postgres

I have these resources:

defmodule Marketplace.Markets.Property.Offer do
  ...

  relationships do
    belongs_to :offeror, Offeror, allow_nil?: false
  end
end

defmodule Marketplace.Markets.Property.Offeror do
  @moduledoc false

  alias Marketplace.Markets

  use Ash.Resource,
    data_layer: AshPostgres.DataLayer

  attributes do
    uuid_primary_key :id

    attribute :email, :ci_string, allow_nil?: false

    attribute :encrypted_phone_number, :binary, allow_nil?: false, private?: true
    attribute :encrypted_first_name, :binary, allow_nil?: false, private?: true
    attribute :encrypted_surname, :binary, allow_nil?: false, private?: true
  end

  calculations do
    alias Marketplace.Ash.Calculations.Decrypt

    calculate :phone_number, :string, {Decrypt, field: :encrypted_phone_number}
    calculate :first_name, :string, {Decrypt, field: :encrypted_first_name}
    calculate :surname, :string, {Decrypt, field: :encrypted_surname}
  end

  relationships do
    has_one :offer, Markets.Property.Offer
  end

  postgres do
    table "users"

    repo Marketplace.Repo

    migrate? false
  end

  actions do
    defaults [:read]
  end
end


When I fetch my offers and try to load the offeror name, ash_postgres will crash:

[offer] = Marketplace.Markets.read! Marketplace.Markets.Property.Offer
Marketplace.Markets.load(offer, [offeror: [:first_name, :surname]])
